They were three trucks down from where Erin Langhofer was enjoying a night out with her boyfriend and friends when a fight broke out between young men.

"He was just from here to here after they finished fighting," Wickam said. "And I'm like, 'He's got a gun. He's got a gun.' And so we're all getting down and then we see him take off. So we're like, 'OK good.'"

But it wasn't over.

Minutes later that man, who police identified as 18-year-old Deon'te Copkney came back. Police said he fired nine shots into a crowd. A stray bullet hit Langhofer in the head.

"And everyone's running," Wickam said. "People are jumping over the truck hiding behind all the food trucks and people scrambling."

"I started tearing up a little bit because I couldn't even imagine losing a girlfriend or daughter. You didn't know what it was at that point, but he was on the ground with his head in his hands," Insalman said.

"I mean you just can't get that out of your head," Wickam said, tearing up. "And like seeing her boyfriend. It was so sad because he's so -- it all happened so fast to him, too. In one second his girlfriend is on the ground."

At just 25 years old, Langhofer lost her life.

"I just feel so sorry for that family," Wickam said. "I feel so sorry for whoever witnessed it because they're going though the same thing, and it's something that never should have happened."
